I want to select a new artist.

You can change artists as long as the number of artists selected does not exceed the limit assigned to your subscription type.
When selecting artists for the first time after paying for the changed subscription ticket, you can use it only after selecting all N artists based on the N-person ticket.
(Example: If you select artists for the first time after purchasing a 6-person ticket, you can select 6 artists and save.) 
If you cannot select artists for a new subscription ticket, please deselect all the artists from the existing ticket and then select and save them in a new subscription ticket.

※ How to change: MY bubble > Subscription

In addition, please refer to the following information for the subscription date with artists.
